Man Matt...you're pretty close. I'm right in the 315 to 320 range. You're right, that thing is a rocket I just can't beleive I'm getting that kind of speed out of my hunting setup.

Rick, sorry about that.They're 7.2 grains per inchwith 100 grain field points and 5 inch vanes and 27" long. You should be able to roughly calculate it. I never actually weighed one of my arrows.
